Calculus Matrices
Use matrices to solve the system of equations, if possible.
2x + y + 2z = 4
2x + 2y = 5
2x – y + 6z = 2
The flow of traffic (in vehicles per hour) through a network of streets is show at the right. Solve the system for the traffic flow represented by xi, i = 1, 2, 3, 4, and 5.
(I have the answers for both: first one (-2a +1.5, 2a + 1, a); second one (x1 = 700 – s – t, x2 = 300 – s – t, x3 = s, x4 = 100 – t, x5 = t) but, I don’t know how to do the work to get to the answers.)
